As part of an institutional program sponsored by the Centre for Teaching Excellence at the Universidad del Norte, Barranquilla, Colombia, we developed an educational research study on two sessions of human anatomy in which we combined team-based learning (TBL) and the use of iPads. Study data included the TBL, assessments applied during the course, student's grades on mid-term examinations and students' perceptions of their experiences. Students reported a positive attitude toward the use of the TBL sessions, and the results showed a significant improvement in their learning between the first and second sessions. Significantly positive correlations (P < 0.05) were obtained between (a) the individual students' readiness test performance 1 and mid-term examination 1, (b) the individual readiness test performances from Session 1 to Session 2, and (c) the group readiness test performances from the first and second sessions. These results point to positive learning experiences for these students. Analyses of the students' reflections on their activities also pointed toward future challenges.

In order to evaluate variation in body fatness by category of frame size (small, medium, and large) during growth, a sample of 7,286 Cuban children and adolescents (3,721 males, 3,565 females) 5-20 years was surveyed. Fatness was estimated from skinfold thicknesses at four sites: subscapular, triceps, suprailiac, and posterior calf. Elbow breadth was used as an estimate of frame size. Generally, the larger the frame size, the greater the amount of subcutaneous fat regardless of age and sex. The results suggest that in the assessment of obesity and its associated risk, in children and youth, frame size, given by categories of elbow breadth, should be taken into account. © 1995 Wiley-Liss, Inc.
